Complete specification is usually accompanied by visual materials such as drawings, plans, or diagrams to better describe the invention. Complete specification must contain at least one claim that is, information which determines the extent of protection sought by the applicant. See a sample of Complete Specification here.
  4. Statement and undertaking under Section 8 is made on Form 03, if applicable.

In case the original general power of authority has been filed in another jurisdiction, that fact may also be mentioned in the self-attested copy.
  7. Priority documents, certified by the Patent office of the jurisdiction where the application for same invention was first filed, are required in the cases of A) Convention Application, and B) PCT National Phase Application wherein requirements of Rule 17.1(a or b) of regulations made under the PCT have not been fulfilled.

What is the process of prosecuting a patent application in India?

  1. Step 01
    The process starts after filing an application for Ordinary Patent or PCT National Phase Patent in India.
  2. Step 02
    The applicant may request an immediate publication of his application.
    Do note that the application would be examined only after it is published, so filing an early publication request helps in expediting the patent examination process.
  3. Step 03
    If an early publication is requested, then the Indian Patent Office shall publish the patent application within the next 10 days.
  4. Step 04
    If the early publication is not requested, then the Indian Patent Office publishes the patent application after 18 months from the priority date.
  5. Step 05
    Filing a request for examination. The request for examination can be filed within 48 months from the priority date. If no request for examination is filed within the 48 months of priority, then the application is ABANDONED by the Patent office. Note that the Indian Patent Office will not examine the patent application unless this request is filed. Hence, if you wish to expedite the patent process, early filing of the examination request is advised. The request for examination can be filed during the entry into the Indian National Phase.
  6. Step 06
    Once the Indian Patent Office receives your request for examination, the application would be examined. During the examination of the application, if the Indian Patent Office is of the opinion that your patent application satisfies all the requirement of patentability, then a patent is granted to your invention.
  7. Step 07
    If the Indian Patent Office is of the opinion that the patent application does not satisfies all the requirement of patentability, then a First Examination Report (FER) would be issued.
  8. Step 08
    The applicant needs to respond to the FER within 6 months from the date of the FER. This period may be extended by further three months by making a specific request. After the response is filed, the Patent Office may issue further examination report to overcome still outstanding objections if any. Do note that issuance of subsequent examination reports by the Patent Office and responding to the same by the applicant must occur within 12 months from the date of the FER. The applicant may request a hearing with the examiner to overcome the objections of the Patent Office.
  9. Step 09
    After submitting the arguments for showing patentability, filing amendments as required, arguing the case in a hearing with the examiner, the Patent Office can either grant a patent or reject granting of a patent. If the Patent Office does not grant a patent, then the applicant may appeal against the decision of the patent Office to the Intellectual Property Appellate Board set up for this purpose.
